My opinion:

Found Gosetsu to be insufferable and obnoxious (never been a fan of the large and loud character archetype)
Solo fight was the same old fight against Imperial forces, just with an annoying, cowardly brute as opposed to the cold, intimidating generals of before.
Omega vs Shinryu was AMAZING (Am I the only one that thought Omega looked cute, fighting Shinryu on equal terms?)
Yda/Lyse reveal wasn't a shock as pretty much the majority had already guessed she was the MNK in the Stormblood Trailer.

Overall, I'd give it a 3/10 with only the Omega vs Shinryu cutscene being the only worthwhile addition to the story.
